Title: Improvements in or relating to electromagnetic relay systems for heavy alternating currents
IPC: H01H9/56
Filed: 1946-10-10
Abstract: 629,541. Switching systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 10, 1946, No. 30308. Convention date, Feb. 2, 1943. [Class 38 (iv)] [Also in Group XXXVII] In an A.C. relay suitable for use in resistance welding wherein it is desirable that the relay should operate either synchronously, i.e. at a precise spot on the A.C. cycle in spite of variations in the moment at which energization begins or isochronously, i.e. at a definite time after the moment at which energization begins, even though the spot on the A.C. cycle of this moment may vary, the time constant of the relay is made smaller than an A.C. period. The relay may be in series with the anode circuit of a gas-filled or vapour-filled discharge tube which is subject to a voltage E, Fig. 2. The grid of the tube is subject to a voltage Es slightly more than 180 degrees out of phase with E. Thus ignition can only occur during the period t and this determines the moment at which energization of the relay begins. Fig. 1 shows how the slight variation of this moment within such a period as t need produce no appreciable change in the moment at which the relay operates or in the operative delay of the relay. In Fig. 1 E represents the energizing A.C. voltage that is going to be applied to the relay and I the lagging current in the relay which would occur if " starting conditions were disregarded. The actual current that flows through the relay will be the sum of this " permanent " current I and a " transient " current if or i<1>f, the latter being determined by the moment at which energization begins and its slope depending on the time constant. If the moment of energization occurs at time t the current will follow the curve i<1>; if at zero time, i.e. at the point A, it will follow the curve i. Considering the positive portions of the curves it will be noted that at any instant the value of il is greater than that of i in spite of its later start. The current level required to operate the relay is shown by W but the precise moment of operation will depend also on the design of the relay. By suitably choosing a design and providing a suitable time constant the relay can be made to operate either synchronously or isochronously.

Title: Improved venting arrangement for clothes dryers and combined washing and drying machines
IPC: D06F25/00
Filed: 1956-10-08
Abstract: 803,337. Washing-machines. GENERAL ELECTRIC CO. Oct. 8, 1956 [Oct. 6, 1955], No. 30632/56. Class 138 (2). [Also in Group XIII] In a tumbler clothes combination washer drier comprising a rotatable perforated drum and an electric heater a single vent element is provided which connects, when appropriate, the interior of the drum with a vent opening or a condenser cooling water supply. A modified element has provision for connection with a washing and rinsing water supply. The elements are such that the condenser water builds up a water seal therein cutting off the gas passage between drum and vent opening. The drier shown is supplied with condenser cooling water through tubing 42, 43, Fig. 2, and a trap 39, Fig. 5, from where it passes into the annular space between the drum 2 and a tub 7 through an opening 56 running down the inner wall 10 of the tub 7 in order to condense the vapour arising from the drying clothes. A V-rib 44 spreads the water over the wall 10. The cooling water and condensate gather in a sump 35 from where they are removed by a pump 46, Fig. 1. The trap 39 has a vent opening 58 to atmosphere. The cooling water builds up a seal in the space between wall 60 and the outer wall such that gas flow from the interior of the drier to the opening 58 is restricted to a small passageway 67. On cessation of cooling water flow through pipe 43 the seal disappears, a passageway 68 being provided for this purpose. Automatically controlled supplies of hot and cold water-for use when the apparatus functions as a washer-flow through a funnel 33 and pipe 34, Fig. 2, to the sump 35. In the modified trap, Fig. 6, the cooling and washing or rinsing waters pass through a pipe 79, the former passing at a lower flow speed than the latter. This causes a build-up of water-seal between walls 75, 83 during cooling water flow but prevents it during washer flow. The vent opening 74 has a restricted access passageway 84 whilst the seal drains away through a hole 85 when the cooling water flow ceases. The drum 2 may be driven at such a speed that centrifugal hydroextraction occurs. The heaters 48, 49, Fig. 1, are controlled by a thermostat 51 using a temperature-sensing element 54. The cooling water flow is automatically stopped when the apparatus door is opened. A device 36 controls the solenoids which control the amount of hot and/or cold washing and rinsing water entering the tub 7. A blowing-out of suds through the pipe 34 and funnel 33 during washing is prevented by connecting the pipe 34 to the bottom of the sump. Specification 792,758 is referred to.

The cables 49, 51 terminate in a junction box 53 and are connected to the motor by a flexible cable 55. A control panel 42 in the space 38 has control members 44 connected by conductors 46a to the corresponding relays 47 whereby any selected motor may be energized. The reset box 54, Fig. 3, includes overload-tripped circuit-breakers 82 . . . 89, each circuit-breaker being in series with a corresponding motor. The circuit-breakers have pivoted arms 82a . . . 89a which move to the dotted-line position when tripped and are reset by a button 52 on the panel 42. The button energizes a solenoid 64 to move a rod 78 against the action of a return spring 80, the rod carrying blocks 68 . . . 75 which engage the arms. The arrangement ensures that all the heavy current conductors connected in the motor circuits are outside the cab and thus undesirable heating of the confined operator space is avoided.

Abstract: 521,447. Sex hormones. SCHERING AKT.- GES. Oct. 26, 1938, No. 31013. Convention date, Oct. 27,1937. [Class 2 (iii)] Compounds of the oestrone series are prepared by reducing to the corresponding diols by means of catalytically activated hydrogen compounds of its formula where R represents a hydroxyl group or a substituent which can be hydrolysed to a hydroxyl group such as an ether or ester group or halogen. The diols may then be subjected to the action of a dehydrating agent, for example hydrobromic acid and acetic acid, or to distillation, whereby water is split off from the two hydroxyl groups, forming a mono-ketone. In the example, 3-methoxy-16 : 17-diketo-oestratetraene (obtained by diene synthesis of 6 - methoxy - 1 - vinyl - 3 : 4 - dihydronaphthalene with 1-methyl-#-1:2-cyclopentenodione (4: 5) ) is hydrogenated in the presence of a Rupe catalyst to give the corresponding diol which on dehydration with hydrogen bromide and acetic acid followed by distillation in vacuo over potassium hydrosulphate yields a monoketone having the composition of oestrone. Specifications 27445/38, as open to inspection, under Sect. 91, 381,758, [Group VI], and 504,082 are referred to.
